Another thing to try, short of new weatherstripping.
Take the door panel off and adjust the tilt of the window frame inward so that it will seal against the stripping.
That old though, the weather stripping has shrunk.
Mine is a 90. I made that adjustment and it helped. Not a total fix.
I keep a towel in the back. There is still one leak that land in my lap when turning left in the rain.
But it is worth it when the sun is out!!!!! no leaks and the wind noise is way cool with the top down!!
